Quinnipiac University’s final pre-election poll[1] suggests Republican Chris Christie has swung back into a narrow lead, 42% to Jon Corzine’s 40%. Corzine had been ahead by 5 points in the previous Q-Poll[2], released last Wednesday.

Independent Chris Daggett is at 12% in the Quinnipiac results. Among Daggett supporters, 38 percent say they might change their mind: 39 percent say Corzine is their second choice, while 29 percent say Christie is number two.

The “poll of polls” concept that averages all the recent polls shows, in the RealClearPolitics[3] version at least, that Christie has a 1.2 percentage point advantage over Corzine.

This close to an election, that math doesn’t include polls from “partisan affiliated” polls — meaning that Public Policy Polling (Dem-leaning, Christie +6), Neighborhood Research (GOP firm, Christie +7) and Democracy Corps (Dem-leaning, Corzine +5) polls from the last week don’t count. Rasmussen, usually considered Republican leaning, is included.
